Hello - I have two files which play back in VLC correctly. They were encoded using this command: ffmpeg -y -i '/tmp/2e905b981d30324f9a0664cbabb3f59a20170406-21128-r0neh9.wav' -acodec libvorbis '/tmp/2e905b981d30324f9a0664cbabb3f59a20170406-21128-r0neh920170406-21128-146yyex.ogg However ov_pcm_total reports a zero length for one of the two files.

Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so long to open OGG file? The OGG file has just 210 MB. It takes a lot of time open the file. I am working on OGG audio recorder and player. Thanks in advance! With kind regards, Pavel

Hi, I'm new to writing any kind of sound program and somewhat new to C. I am on linux and I've been trying to get the example code (http://www.xiph.org/ogg/vorbis/doc/vorbisfile/example.html)for the decoder using libvorbisfile to work. I think my main problem is output to /dev/dsp. If I use the example where the only change I made were to open a file instead of using stdin and I ouput

Help is needed ! I cannot extract infos from video stream in an .ogm file using the VorbisFile library. It seems that I can only open .ogg files (audio)! When I call "ov_open_callbacks" it generates a message error. Here is my procedure in pascal: code: _____ procedure GetOGMInfo; var F : TFileStream; vf: OggVorbis_File; res: integer; begin F :=

Okay - so I stepped through the code slowly this morning making notes as I went. And I can see what’s wrong. The last Ogg header of the troublesome file contains -1 as the granule position. The spec says this has a special meaning "A special value of '-1' (in two's complement) indicates that no packets finish on this page." 4F 67 67 53 00 04 FF FF FF FF FF FF FF FF 16 A2

Hi All, I am trying to program the 'Tremor' decoder onto an array of Processors. I am using four Processors. I did this experiment: I split the while(!eof){} in the main() in to four tasks using if(!eof) statements. In this modification, each if() decodes one packet of data at-a-time, sequentially. Then, I ran the code on a single Processor and the decoding was successful. The

I'm considering patching my copy of ogg123 to support vorbisgain tags. Is there any interest in folding this sort of patch into the main line ogg123? Has anyone done this already (or to another command line ogg player)?

hi, i`m trying to use the plot function to show more variable-funktions in one graphic. so for example i would like to show Chinas Income in different sectors in one graphic. obviousely typing plot(ChinaIncome) the graphics are split and there is one graphic for agriculture, one for industry.... i would like to put them togheter in one graphic, maybe with different colors for every function,

I am trying to integrate a Nortel Norstar system with an Asterisk service using a TDM04B card (4 fxo). So far everyting works from Asterisk to Nortel. The problem is when someone dials from the Nortel PBX to the Asterisk server. Asterisk answers the call and provides a dialtone (with DISA) but appartently the DTMF tones are not passed to asterisk and the call cannot proceed. This only

Hi! I'd like to encode from a 22050 Hz source wav file (only in that case), but i get the following error message: "Invalid floating point operation" I use delphi: vorbis_encode_init_vbr(vi,2,22050,0.5) . . .

As for VBR, just try it. :) --- >8 ---- List archives:

I am trying to write a module for tripwire. I need to push out the twcfg.txt and twpol.txt files only if the tw.cfg and tw.pol files do not currently exist. How can do I this with File{}? I''m can''t seem to find a way to do it. In general times, how can you deploy file A only when file B does not exist? And... tripwire... what a mess. I am trying to use push out the site key,

Hi Gunter, I think this problem started happening when I upgraded from Debian Wheezy to Debian Jessie. If nothing looks amiss in my code, it probably is a sound driver problem. But since it works 100% of the time in ogg123, I feel I must have missed some corner case. My audio driver is almost always active. I usually have my music player going in the background when I do my testing. The problem

I'm looking at the vorbis_synthesis_blockin and pcmout functions, and I'm confused about the positioning and determination of centerW wrt adding in the next set of data. Specifically, it seems legal (in vorbis_synthesis_pcmout) to return to the user any data up to the centerW position; however, in vorbis_synthesis_blockin, if you have a long block following a short block, it is legal to

Hi! In the SDK documentation it is written: "base_quality Desired quality level from 0.0 to 1.0" But, i can give less than 0 parameter too. Why? Although, if i give greater than 0.9, encoding is halt with "floating point division by zero" message. Why? Thank you for your reply, crc --------------------------------- Do you Yahoo!?

Hi Gunter, I've solved the sound glitch. Since it was hard to reproduce, it took me a while, but I eventually figured it out. What I needed to do was fill the buffer with more data before handing it off to ao_play. It requires lots of bookkeeping, pointer arithmetic, and a sufficiently large buffer. First, the bigger buffer. I just pulled this code from ogg123: #define PRIMAGIC
